Heritage Story
At 25, while working at Louis Vuitton in Hong Kong, the founder purchased her first Alma bag and kept it for 30 years, dreaming of passing it to her daughter. Though the bag’s style no longer resonated, the lock and key captivated her daughter’s heart. Today, this sentimental heirloom lives on in a one-of-a-kind necklace set, symbolizing connection across generations.
Styling Tips
Pair the gold-plated lock and key chains over a crisp white blouse for a classic look, or layer both lengths against a dark turtleneck for modern contrast. The rhodium set adds an edgy sheen—perfect with leather or denim.
